In simple words: This code describes different types of bumps or lumps under the skin that form around hair follicles.These lumps can be filled with fluid or other substances.

This ICD-10-CM code encompasses various types of cysts originating from hair follicles or related structures within the skin and subcutaneous tissue.Specific subtypes include epidermal cysts (L72.0), trichilemmal cysts (L72.1), steatocystoma multiplex (L72.2), and other specified follicular cysts (L72.8).An unspecified follicular cyst is coded as L72.9.

Example 1: A 35-year-old patient presents with a slowly growing, painless nodule on their back. Physical examination reveals a firm, fluctuant mass consistent with an epidermal cyst (L72.0).The cyst is excised and sent for histopathological examination., A 50-year-old patient complains of multiple small, firm cysts on their scalp.Physical examination shows numerous pilar cysts (L72.1). The patient is counseled on conservative management options and the possibility of surgical excision for cosmetic reasons., A 20-year-old presents with multiple, soft, fluctuant cysts on their face and neck. Examination reveals steatocystoma multiplex (L72.2).The patient's family history is reviewed for similar conditions, and treatment options are discussed.

Detailed medical history, physical examination findings (size, location, consistency, number of cysts), imaging studies (if performed), histopathological examination report (if applicable), and treatment plan.

** This code is primarily used for billing and reimbursement purposes in healthcare settings. Accurate coding requires detailed documentation, including the type of cyst and clinical context.
